MSSA Rokide® ceramic flame spray rods deliver highly wear-resistant coatings that protect metal & non-metallic surfaces in high-temperature, abrasive and corrosive environments.
Rokide® rods optimize deposition efficiency while providing high particle-to-particle cohesive bonding. The process creates hard, chemically inert coatings far superior to those provided by powder systems. Thicker coatings of up to 0.80 mm (0.030 inch) can be applied with the same thermal-resistant, chemical-resistant & electrical-resistant quality. The bottom line: An excellent surface finish that guarantees predictable performance & longer life in a cost-effective process across a wide range of demanding applications.
Used with a preliminary layer of Rokide® Ni-Chrome Bond Coat, Rokide® flame spray rods yield the ultimate coating solution to extend the life of parts & equipment.
